PREPARE FOR THE ASSESSMENT YOUR SCHOOL NAMES
NNAT and CogAT: how the preparation differs
NNAT3 and CogAT are different assessments. A family familiar with CogAT should confirm the school’s actual test before carrying over a practice plan, level label or score interpretation.

The practical distinction for families
NNAT3 uses nonverbal visual problems. CogAT covers verbal, quantitative and nonverbal reasoning batteries. Both can involve reasoning, but a preparation page written for one should not simply be relabeled as the other.
This comparison explains how to choose a learning path. It is not a claim that either test is better for every child or that their scores can be directly exchanged.
What can carry over?
- A calm routine and clear directions.
- Independent attempts before hints.
- Reviewing a specific missed relationship.
- Separating learning practice from timed rehearsal.
What needs to change?
| Preparation detail | What to check for NNAT3 |
|---|---|
| Level label | Use the NNAT3 A–G assignment rather than assuming the same numbered or grade-based label. |
| Practice content | Focus on the visual problems relevant to the assigned assessment. |
| Timing and form | Use NNAT3’s published format as context; do not import CogAT battery timing. |
| Scores | Read the NNAT report’s labels; do not convert a CogAT or practice score into NAI. |
A sensible next step
If the school names NNAT3, read the NNAT overview, confirm the assigned level and explore original visual samples. If the school names CogAT, use the corresponding CogAT resources rather than purchasing practice based only on a familiar brand name.
